High tech and sturdy air operated valve, with a floating plug seal, meeting stringent use criteria.Օ An extra thick body of the actuator and of the valve, ensuring a good resistance to mechanical and thermaldistorsions. A modular design enabling the following configurations: Օ Shut off valveDCX3 LDCX3 TDCX3 X Divert valveDCX4 L/LDCX4 T/LDCX4 L/TDCX4 L/XՕ PFA seals quality ensures a complete sealing at high temperature and a good resistance to aggressive products. Plastomer seal can be replaced by elastomer sealՕ Single or double acting connection With plastomer seal, vertical setting up...

High tech, mix proof valve, with two independent plugs meeting stringent use criteria.Օ Fitted with an extra thick body of the actuator and of the valve, ensuring a good resistance to mechanical andthermal distortions. Possibility to actuate the two plugs independently and to clean the chamber area, plugs closed, thanks to a doublewall leak detection channel.Օ Partial balancing of the pressure under the lower plug thanks to a protected counterbalance. PFA seals ensure a complete sealing at high temperature and a good resistance to aggressive products (easily cleaned). Օ The design of the...

Valve closed Valve open > The upper and lower lines are isolated by a releasing chamber allowing the protection of both lines, and the visualization of a possible leak. Both plugs closed against each other, preventing leakage. Remarks: Depending on the process, it is sometimes possible to use the stroke of one plug only to clean the valve completely. When the valve doesnt need particular cleaning, it can also be used without break away actuator. It is possible to clean the leakage chamber, when the valve is closed, by inserting a special fitting into the tapped center hole at the bottom of...

VCDI-PMO Mixproof Valve VCDI-PMO Mixproof Valve > In order to meet the standards administered by the Pasturized Milk Ordinance, the VDCI-PMO Mixproof valvewas developed. This valve incorporates an enlarged leak path that is equal in ID dimension to the valve port size. The VDCI-PMO Mixproof valve is manufactured with the same characteristics and options as the standard VDCI Mixproof valve. Note: The standard position feedback equipment can be complimented with proximity switches to detect thevalve plugs are raised during air space and leak path CIP operations. 13 size="-1">
